US STOCKS-Economic slump worry hits market; GM plunges

(Updates with market falling further)

NEW YORK, Nov 10 (Reuters) - U.S. stocks fell on Monday as doubts about whether China's stimulus plan would avert a deep global economic slump surfaced and investors fretted about General Motors' (GM.N: Quote, Profile, Research) outlook.

Shares of GM slid nearly 26 percent to $3.23 after Deutsche Bank's recommended a "sell" and slapped a price target of zero on the stock, a Dow component.

The Dow Jones industrial average .DJI was down 14.73 points, or 0.16 percent, at 8,929.08. The Standard & Poor's 500 Index .SPX was down 5.96 points, or 0.64 percent, at 925.03. The Nasdaq Composite Index .IXIC was down 14.74 points, or 0.89 percent, at 1,632.66. (Reporting by Ellis Mnyandu; Editing by Jan Paschal)
